Master Design Patterns with Dependency Injection: Build Robust & Maintainable Software

Learn to apply essential design patterns for building clean, adaptable, and maintainable software. This course focuses on the most frequently used patterns that developers must know, going beyond theoretical knowledge to practical implementation. We'll delve into how to effectively use these patterns alongside Dependency Injection and SOLID principles to create truly robust applications.

What You'll Learn:

• Core Design Patterns: Gain a deep understanding of key patterns, including:
  • Decorator Pattern: Dynamically add responsibilities to objects.
  • Composite Pattern: Represent hierarchical structures of objects.
  • Proxy Pattern: Provide a surrogate or placeholder for another object to control access.
  • Strategy Pattern: Define a family of algorithms and make them interchangeable.
  • Adapter Pattern: Convert the interface of a class into another interface that clients expect.
  • Null Object Pattern: Provide a default object to avoid null checks.
• Dependency Injection (DI): Master Constructor Injection and understand how to decouple components for increased flexibility and testability.
• SOLID Principles: Learn and apply the fundamental principles of object-oriented design for creating well-structured and maintainable code.
• Composition Root (Bootstrapping): Understand how to properly initialize your application's components.
• Object Graph: Learn to manage complex relationships between objects.
• Pattern Combination & Reuse: Discover how to combine and reuse design patterns for optimal results.

Who is this course for?

This course is designed for:

• Beginner Programmers: Build a solid foundation in object-oriented design.
• Experienced Developers: Enhance your skills and improve the maintainability and adaptability of your code.
• Developers seeking to improve their understanding of software architecture and design.

While familiarity with interfaces, abstractions, and interfaces is helpful, basic knowledge of classes and functions is sufficient. Developers facing challenges with code maintainability and adaptability will particularly benefit from this course.

Course Content & Approach:

• Practical Examples: Each design pattern is explained using relatable analogies and practical code examples (e.g., the "Plug and Socket" analogy).
• UML Diagrams: Simple UML diagrams visually illustrate the patterns and their application.
• Video Lectures: Engaging video lectures explain concepts and demonstrate implementations.
• Presentations: Concise presentations summarize key takeaways.
• Screencasts: Watch real-time code implementations.
• Hands-on Exercises: Reinforce your learning with self-contained exercises.
• Quizzes: Test your understanding with quick self-assessments.
• Comprehensive Final Test: Assess your overall knowledge with a 35+ question exam.

Real-World Application:

We'll apply these concepts to a practical example: E-commerce Order Processing. You'll learn how to integrate design patterns into a real-world application to improve its flexibility, maintainability, and understandability.

Coding in C#:

All examples and exercises are written in C#, a clear and easy-to-understand programming language. The concepts are transferable to other object-oriented languages.

Exercises & Testing:

The course includes exercises written in C# that you can complete using the Udemy IDE (with built-in testing and solutions) or in a separate project folder for Visual Studio 2022 Community Edition (or later). All code examples and exercises are thoroughly unit-tested, providing valuable insights into Test-Driven Development (TDD).

Unlock the Power of Design Patterns:

Don't let theoretical knowledge remain abstract. This course provides the practical skills you need to effectively implement design patterns and build software that is adaptable, maintainable, and easy to understand.
